I personally think it would sound better with drums, but what the fuck do I know. The drum beat you use was a nice change from the usual beats. Reminds me of something off Quake on the Sega Dreamcast. That had cool fucking music! If you like kick ass brutal metal, check out my "This is Fucking Grindcore" track.
that may of only been a demo of summit that u didnt go thro with but personally i think u have done quite well and should finish it off.
Well done. :)
